问题
I am trying to run parse server with nodejs in ibm bluemix but it is throwing an error in parse server PromiseRouter file.
PromiseRouter.js:48
throw _iteratorError;
^
ReferenceError: Symbol is not defined
How can i get this resolved
My App .js
var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var app = express();
var port = process.env.PORT || 1337;
// Specify the connection string for your mongodb database
// and the location to your Parse cloud code
var api = new ParseServer({
databaseURI: 'mongodb://IBM_MONGO_DB',
cloud: './cloud/main.js', // Provide an absolute path
appId: 'MYAPPID',
masterKey: 'MYMASTER_KEY', //Add your master key here. Keep it secret!
serverURL: 'http://localhost:' + port + '/parse' // Don't forget to change to https if needed
});
app.use('/parse', api);
app.get('/', function(req, res) {
res.status(200).send('Express is running here.');
});
app.listen(port, function() {
console.log('parse-server-example running on port ' + port + '.');
});
Response :

This is the function in PromiseRouter.js that is throwing an error
PromiseRouter.prototype.merge = function (router) {
var _iteratorNormalCompletion = true;
var _didIteratorError = false;
var _iteratorError = undefined;
try {
for (var _iterator = router.routes[Symbol.iterator](), _step; !(_iteratorNormalCompletion = (_step = _iterator.next()).done); _iteratorNormalCompletion = true) {
var route = _step.value;
this.routes.push(route);
}
} catch (err) {
_didIteratorError = true;
_iteratorError = err;
} finally {
try {
if (!_iteratorNormalCompletion && _iterator.return) {
_iterator.return();
}
} finally {
if (_didIteratorError) {
throw _iteratorError;
}
}
}
};
This is all i have
回答1:
The reason why Symbol
is not found is because it is an ES6 feature that is not supported in your current Node.js build. Check to make sure your Node.js runtime is at least v4 (see compatibility here).
The easy way to ensure your Node.js build on Bluemix is running at least v4.0 is to define your engine
variable in your app's package.json
file as such:
{ "engines" : { "node" : ">=4.0" } }
After updating your package.json
file, re-push your application to Bluemix and it will build it with your defined version of Node.js
